△ Ambient air temperature
The ambient air temperature does not exceed +40℃. The average value within 24 hours does not exceed +35℃: the lower limit of the ambient air temperature is -5℃,
△ Transportation and storage
The ambient air temperature is between -25℃ and +60℃, and can reach +70℃ (within 24 hours)
Altitude: The altitude of the installation site does not exceed 2000m
△ Atmospheric pressure condition humidity: When the maximum temperature is +40℃, the relative humidity of the air does not exceed 50%. Higher relative humidity can be allowed at lower temperatures, for example, when the air temperature is +20℃, the relative humidity is 90%. Special measures should be taken for condensation occasionally caused by temperature changes.
△ Pollution level: Level 3
△ Electrical compatibility level: Environment B
